I have only seen one other of these. They are apparently rare, but it is most assuredly a Takahashi 12mm ortho of the same design as all the others. Superb planetary eyepiece, second only to the Pentax at twice the price. I apparently don't have a factory box but do have other boxes to ship in. $110 plus shipping. Have .965 to 1.25" adapter also if you need one for $9 extra. Would discuss trades for quality something. Fred
